18. Sparse Array Architectures for Wireless Communication and Radar Applications
Abstract : This thesis focuses on sparse array architectures for the next generation of wireless communication, known as fifth-generation (5G), and automotive radar direction-of-arrival (DOA) estimation. For both applications, array spatial resolution plays a critical role to better distinguish multiple users/sources. READ MORE

19. Wafer-scale Vacuum and Liquid Packaging Concepts for an Optical Thin-film Gas Sensor
Abstract : This thesis treats the development of packaging and integration methods for the cost-efficient encapsulation and packaging of microelectromechanical (MEMS) devices. The packaging of MEMS devices is often more costly than the device itself, partly because the packaging can be crucial for the performance of the device. READ MORE
